SVGGraph options: guideline_text_colour

The datatypes used in this documentation for specifying SVGGraph options
are described below. All options can be a literal value of the data type
described, a variable containing the data type, or an expression that will
produce the data type when evaluated (and they must always be valid PHP
expressions).

array

An array(), the number and data types of its members will
depend on the option for which is it used.

boolean

A boolean TRUE or FALSE value, or any values
that convert easily such as 1, "1", 0
and "".

callback

A callable function, which can be either the name of a function or an
anonymous function itself.

colour

Any of the colour values supported by SVG inside a single or double
quoted string. These include three and six digit hex codes, RGB and
RGBA colours, and colour names. SVG uses "none" for no colour,
which generally leaves things transparent.

fill

A colour value or one of the gradients and patterns supported by
SVGGraph. See the SVGGraph colours page
for details.

integer

A negative or positive whole number or 0.

number

Any number supported by PHP, for example 1 or
-3.2 or 1.63e5 or M_PI.

string

Single or double quoted strings. Remember to double-quote your strings
if you are inserting a line break: "Line 1\nLine 2".

Per-dataset options allow specifying one option for all datasets or an
array of options to be used for each dataset in turn. If there are more
datasets than entries in the option array, the sequence will be repeated.

For this example, the widgets for all datasets will taste of banana. The
graph will use red widgets for dataset 0, green widgets for dataset 1 and blue
widgets for dataset 2. Dataset 3 repeats the sequence so its widgets will be
red, dataset 4 will have green widgets and dataset 5 will have blue
widgets.
